To just summarize the long story, my DP's father is constantly introducing new girlfriends to us. He splits up with one, next week he's got another. I don't really care what he does with women, as long as we don't have to meet every single one of them.
As an example, in our DS's first bday he showed up with a random girl that he met that same week, then he met another and left this one... The thing that is annoying me is that now he's playing with two, so he comes here and talks rubbish about n#1, then brings her home to visit us; talks about private life of n#2, then we meet for dinner... I can't stand this, I feel like my house is a date site, and he always says to our DS 'give a kiss to grandma' which I believe that as well of being disgusting what is he doing, he's confusing our son.
I told DP to tell him to stop and when he can actually stay with one long enough then he can come and introduce her properly, but of course, my partner is used to his father and wouldn't care/ just mock the situation.
IABU / behaving like an old woman? or I am actually right to feel like confronting him?
I know this is not like a big deal or real problem but I honestly need to ask for objective opinions. Thank you.
